Playwright is a framework for browser automation. It has bindings for both JavaScript and Python.

Laminar excels at tracing browser agents by providing unified visibility into both browser session recordings and agent execution steps.

​
Playwright integration

Laminar has a native integration with Playwright for both JavaScript and Python. You simply need to initialize Laminar with your project API key and Playwright will be traced automatically. We will hook into the API to create OpenTelemetry spans, but more importantly, we record browser session recordings.

import { Laminar } from '@lmnr-ai/lmnr';
import { chromium } from 'playwright';

Laminar.initialize({
  projectApiKey: process.env.LMNR_API_KEY,
});

// The rest of your playwright code

For some setups, you may need to pass the module to the Laminar.initialize function. For example,

import { chromium } from 'playwright';
import { Laminar } from '@lmnr-ai/lmnr';

Laminar.initialize({
  projectApiKey: process.env.LMNR_API_KEY,
  instrumentModules: {
    playwright: {
      chromium
    }
  }
});
